Dilip Sarkar, renowned for his meticulous research, delves into the Battle of Britain in this first volume of an eight-part series. His evidence-based approach offers a comprehensive view of the 1940 aerial conflict, exploring the development of air power, Britain’s defense, the German strategy, the Home Front, and political events. Sarkar goes beyond the well-known narrative, revealing new human stories and events. The book traces the conflict's background, including the German invasion of Norway, the Fall of France, and the air battles over Dunkirk. Sarkar questions the official start date of the Battle of Britain, arguing that the fighting began earlier, on 2 July 1940. A detailed, day-by-day account follows, acknowledging aircrews lost before 10 July and recognizing contributions from Bomber and Coastal commands, not just the pilots of Spitfires and Hurricanes. Sarkar’s research, based on official sources and personal accounts, challenges many myths and the accepted narrative. This work is more than a record of combat losses; it’s a deep dive into the broader context of the battle, drawing on unique firsthand accounts, intelligence reports, and political documents. It’s an unprecedented look at the Battle of Britain and its far-reaching implications.
